This is a fairly recent problem, the last week or so on servers that have run fine for months and months. The only thing I can find is a log entry right before the reboot: /kernel: st0(ahc0:1:0): Sequential-Access density code 0x13, drive empty It *looks* like an attempt to backup to tape, but no backups are being run. I even had the backup script (run out of cron) log attempts before beginning the backup, thinking that our scheduling system was out of whack. Nothing appeared. The only thing I can think of is that we recently stopped keeping tapes in the drive overnight, we used to pop out the day's tapes and pop in the next day's right away. Does FreeBSD, for some reason, occasionally check the tape drives? To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
